Like the Lotus Elise, the canvas top on the 4C Spider isn't some fancy automatic roof. Instead, owners will need to manually sort things out. Unlike the Elise, at least, the 4C's top is easier to manage when both fixing and removing from the mid-engined sports car's body. For those that prefer the security provided by a hard top, a removable carbon-fiber roof will be added after launch. Aside from that change, most of the tweaks for the 4C Spider have to do with options and equipment.
As we explained in our original post, opting for the topless version of this turbocharged Italian will still get you to 60 in just 4.1 seconds, while Alfa claims the 4C Spider can still pull 1.1 lateral g.
